As best seen from the exploded view of FIG. 2, the membrane horn switch 10 comprises a first switch half 12 and a second switch half 20. The first switch half 12 has a thin, flexible front plate 14. The front plate 14 is made of an insulating material such as a suitable plastic material, for example MYLAR® polyester or polyethylene, and the front plate 14 has a thickness of about 0.13 millimeters. The thin flexible front plate 14 includes a conductive coating 16 on its inner surface. The conductive coating 16 may be applied to the flexible front plate 14 by any suitable means, such as by printing conductive ink onto the flexible front plate 14. The electrical connection to conductive coating 16 is formed by crimping electrical wire 18 onto conductive coating 16 at location 17. The distal end of wire 18 terminates in electrical terminal 19. In addition, a raised pattern of insulating material 15 forming a local pattern may be applied on the front surface of the flexible front plate 14 to form a force concentrating area for the horn switch 10. .
【０００７】 第２スイッチ半体２０は、ポリエステルなどの適切な材料からなる剛固な後板 ２２を具備し、この後板２２は、所望の剛性を与えるように約１ミリメートルか ら約２ミリメートルまでの厚さを有する。後板２２用に他の材料、例えば剛固な ガラス繊維が用いられることもできる。この場合にはこの材料、即ちガラス繊維 が有する追加の剛性のために、約０．８ミリメートルの厚さしか必要とされない 。また、剛固な後板２２の前方表面上には導電性コーティング２４が設けられる 。この導電性コーティング２４もまた、剛固な後板２２の前方表面上に導電性イ ンクを印刷塗布することによって構成されることができる。また、予め定められ た適切なパターンをなす誘電材料体２６が第２スイッチ半体２０に付けられて、 警笛スイッチ１０の早過ぎる短絡（ショート）を防止するようにする。誘電材料 体２６が、望ましくない短絡を防止するために二つのスイッチ半体１２，２０を 分離することができさえすれば、誘電材料体２６は、第１および第２のスイッチ 半体１２，２０のいずれか一方または両方に付けられることができるということ を理解されたい。また、誘電材料体２６の厚さ及び関連した形状またはパターン は、警笛スイッチ１０の感度を変化させるのに利用されることができる。第２ス イッチ半体２０への電気的接続は、位置３０において導電性コーティング２４上 に圧着された電線２８によって形成される。警笛スイッチ１０が作動させるよう になっている警笛（クラクション）（図示しない）を作動させるのに使用される 外部電気回路に第２スイッチ半体２０を接続するために、電線２８の他方の遠位 端部は電気端子３１を含む。The second switch half 20 comprises a rigid rear plate 22 made of a suitable material such as polyester, which rear plate 22 has a length of about 1 millimeter to about 2 millimeters to provide the desired stiffness.

At the time of assembly, the holes 40 of the horn switch 10 are positioned on the columns 38 so that the columns 38 pass through the holes 40. The horn switch is then crushed by mushrooming the distal end 42 of the strut 38 to obtain a thermal staking, for example by using ultrasound or other suitable type of heat. 10 is attached to the airbag cover 33. The horn switch 10 can be attached to the airbag by using various types of thermal bonding methods along the outer periphery or by using thermal rivets. No matter what process is used to attach the horn switch 10 to the airbag cover 33, the horn switch 10 will not be separated from the airbag cover 33 when the air bag is inflated. It should be understood that the airbag cover 33 must be firmly attached.
【０００９】 警笛スイッチ１０は、熱的成形操作を用いることにより、エアバッグカバー３ ３の形状に適合した輪郭に形成されることができる。第１スイッチ半体１２の可 撓性前板１４の前面上の局所的***部域１５は、エアバッグカバー３３の前面が 押されたときに警笛スイッチ１０のこれらの局所的***部域１５上にかかる荷重 を集中化させる。これにより、これらの局所的***部域１５は、警笛スイッチ１ ０を作動させるのに必要とされる力を低減させる。The horn switch 10 can be formed into a contour that matches the shape of the airbag cover 33 by using a thermal molding operation. The local ridge areas 15 on the front surface of the flexible front plate 14 of the first switch half 12 are on these local ridge areas 15 of the horn switch 10 when the front surface of the airbag cover 33 is pushed.
